Nguyen Anh Quynh 2f28f3f210 unit: make test_x86_soft_paging.c compilable. also update .gitignore for its binary 2016-02-22 14:01:00 +08:00
Ramirez57 2ab2b229ce test case: x86 guest paging 
Test case for x86 paging using virtual addresses mapped by Unicorn, as well as unmapped.

Attempting to read/write from virtual address ranges unmapped by Unicorn wrongly causes protection faults, even when the virtual address points to read/write regions of Unicorn memory.

Pull Request for Issue #364: Invalidating Translation Cache after self-modifying code
 2016-01-31 10:37:04 +08:00
steve fc22a359e2 Issue #364 - Move RIP/PC closer next to the offending self-modifying code 
which modified the 2nd next instruction (imul) in which that escaped
our wonderful ability to invalidate the
instruction translation cache in which we badly need to pick up the
self-modification being made.

Nguyen Anh Quynh 9e64cba6ec Rename some hook related enums: 
- UC_ERR_READ_INVALID -> UC_ERR_READ_UNMAPPED
 - UC_ERR_WRITE_INVALID -> UC_ERR_WRITE_UNMAPPED
 - UC_ERR_FETCH_INVALID -> UC_ERR_FETCH_UNMAPPED
 - UC_MEM_READ_INVALID -> UC_MEM_READ_UNMAPPED
 - UC_MEM_WRITE_INVALID -> UC_MEM_WRITE_UNMAPPED
 - UC_MEM_FETCH_INVALID -> UC_MEM_FETCH_UNMAPPED
 - UC_HOOK_MEM_READ_INVALID -> UC_HOOK_MEM_READ_UNMAPPED
 - UC_HOOK_MEM_WRITE_INVALID -> UC_HOOK_MEM_WRITE_UNMAPPED
 - UC_HOOK_MEM_FETCH_INVALID -> UC_HOOK_MEM_FETCH_UNMAPPED
 - UC_HOOK_MEM_INVALID -> UC_HOOK_MEM_UNMAPPED

This also renames some newly added macros to use _INVALID postfix:

 - UC_HOOK_MEM_READ_ERR -> UC_HOOK_MEM_READ_INVALID
 - UC_HOOK_MEM_WRITE_ERR -> UC_HOOK_MEM_WRITE_INVALID
 - UC_HOOK_MEM_FETCH_ERR -> UC_HOOK_MEM_FETCH_INVALID
 - UC_HOOK_MEM_ERR -> UC_HOOK_MEM_INVALID

Fixed all the bindings Java, Go & Python.

Nguyen Anh Quynh 90eb8f2e72 This commit continues the PR #111 
- Allow to register handler separately for invalid memory access
- Add new memory events for hooking:
   - UC_MEM_READ_INVALID, UC_MEM_WRITE_INVALID, UC_MEM_FETCH_INVALID
   - UC_HOOK_MEM_READ_PROT, UC_HOOK_MEM_WRITE_PROT, UC_HOOK_MEM_FETCH_PROT
- Rename UC_ERR_EXEC_PROT to UC_ERR_FETCH_PROT
- Change API uc_hook_add() so event type @type can be combined from hooking types
